Potts, Wayne K. | Emigration behavior of Clark's Nutcracker | Eruptive movements of the Clark's Nutcracker (Nucifraga columbiana) were observed during the late summer and fall of 1977, 1978 and 1979 in northern Utah and adjacent states. Over 2,000 emigrating nutcrackers were seen during these periods. Eruptions began in mid to late August, about the time nutcr... | Breeding range; Flocks; Observations | 1981 |

Parkinson, John Stansfield | Genetics of bacterial chemotaxis | Many types of motile bacteria are capable of detecting and responding to changes in their environment. Phototactic, chemotactic and thermotactic movements in bacteria are similar to more complex behaviours seen in higher organisms, and constitute useful model systems for investigating the molecular ... | Bacterial chemotaxis | 1981 |

Olivera, Baldomero M.; Gray, William Robert | Peptide toxins from Conus geographus venom | The biochemical characterization of three highly toxic peptides from the venom of the marine snail Conus geographus is described in this report. These peptides cause their potent activity by inhibition of the postsynaptic terminus of the vertebrate neuromuscular junction. The relatively small size o... | Conus geographus; Venom; Conotoxins; Neurotoxins | 1981 |

Olivera, Baldomero M.; Hillyard, David R. | Pyridine nucleotide cycle: studies in Escherichia coli and the human cell line D98/AH2 | Different metabolic steps comprise the pyridine nucleotide cycles in Escherichia coli and in the human cell line HeLa D98/AH2. An analysis of the "P-labeling patterns in vivo reveals that in E. coli, pyrophosphate bond cleavage of intracellular NAD predominates, while in the human cell line, cleava... | Nicotinic acid; Turnover cycle; DNA ligation; Nicotinamide | 1981 |
